From the project
Test board for the Guerrilla RF GRF5604 RF amplifier integrated circuit
Standalone RF power amplifier module for the LinHT handheld, built around the Guerrilla RF GRF5604. This repository houses a proof-of-concept (PoC) board used to evaluate matching, biasing, efficiency, and linearity in the 420–450 MHz band. Results from this effort will feed back into, and eventually be integrated with the main LinHT hardware project.
- Design tested - works. - Tuning follows the vendor's reference design for 397–470 MHz
